Madagascar Euphorbia Culture
I have recently acquired several Euphorbia from Madagascar. Most are difficult to find specific cultural information. The kind of knowledge one only develops with time and knocking off a few plants. These weren't cheap and I would like to avoid as many mistakes as possible. I have done some research at Succulent Euphorbia and Bihrmann's Caudex and Cactuspedia but find it confusing when one site says, "Do this" and another says something different or not specific. What does, "Some water and some sun" actually mean? Bottom line, if any of you have personal knowledge about the culture of the following, please post or email me. It's not that I haven't grown Euphorbia before but some of these might take a bit "extra care" and some helpful words would certainly go a long way. I know your growing conditions may/are different than mine but I think I can figure it out with your help.
Euphorbia alfredii - I think I have this one figured out
E. ankarensis - pretty much the same care as above
E. cremersii - this one is tough, "Some water...No water???"
E. clavigera - not too much water and full sun
E. esculenta - not too much water and full sun
E. neuhumbertii - think I have this one, too
E. poissonii - very hard to find anything out about this one
